WebMay 30, 2011 · 1. Bob S said: Use diameter of 900,000 miles and distance of 94 million miles. So linear subtended angle is d = 9.57 milliradians = 32.9 arc-minutes. So radius is 16' and area is pi R 2, so solid angle is pi x sin 2 (16') = 7.2 x 10 -5 sterads. This derivation is not clear to me. You say that "radius is 16' ", so you're equating a length to an ... WebHere the angle QAP is 32' or 32/60=0.533 degrees. Thus the ratio of the angle QAP to the angle that takes you once around the circle is 0.533 to 360. Thus the ratio of the length of the arc PQ to the circumference of the circle is also 0.533 to 360. In either case I get that the diameter of the sun is approximately 865,000 miles.
